Freeway, Houston, Tex. 77022 Filed Nov. 26, 1968, Ser. No.779,195 Int. Cl. A47k J/14 US. Cl 4-287 4 Claims ABSTRACT OF THEDISCLOSURE An intake control for disposal units mounted in a kitchensink, and the like, that sits in the intake conduit of the disposal unitand has a lower member in which an outlet passageway is formed, an uppermember mountable in said lower member, said upper member havingperforations therein and an outlet valve and valve stem, said unithaving means for sealing the discharge conduit, and being removable fromsaid discharge conduit by merely lifting same out of the conduit intakeopening.

SUMMARY OF THE INVENTION A disposal intake control having a lower memberadapted to seat in the upper end of a disposal conduit, and having adischarge opening in said lower member, and an outwardly projectingflange on the upper margin of said lower member, a yieldable membermounted on and covering said projecting flange, said lower member havinginternally threaded connecting means adjacent the upper end thereof, andan upper unit having a plurality of perforations, and having its uppersurface threaded adjacent the lower margin of said member to be engagedwith the threads of the lower member, and a manually operated valve insaid upper unit adapted to seat in the discharge opening of the lowerunit, said valve opening and closing the discharge conduit and the uppermember restricting the size of particles passing into the disposalintake conduit.

The invention is more particularly described in the followingspecifications and illustrated in the accompanying drawings, wherein:

FIG. 1 is an exploded view of the unit, partially in cross section, and

FIG. 2 is an elevational sectional view of the device mounted in adisposal intake conduit.

In the drawings, the numeral 1 designates a sink in which the disposalunit conduit 2 is mounted. The lower member 3 is semi-spherical, and hasthe discharge opening 4 which is tapered inwardly, and which receivesthe valve 5 to close the discharge intake conduit 2. The upper margin ofthe member 3 has the outwardly projecting annular flange 6 upon which ismounted the resilient sealing member 7, the member 7 having the internalannular groove 8 adopted to receive the flange 6.

The upper end of the lower member 3 is internally threaded, as at 9, toreceive the external threads 10 of the upper member 11. The upper member11 has a plurality of drain openings, as 12, 12, of the desired size,and has the axial square valve stem opening 13. The valve stem 14,integral with the seat 5, is mounted in the upper member 11 through thesquare opening 13. The valve stem is square over the upper portionthereof as at 14, and is reduced and rounded as at 15, over thelowermost portion, and the valve 5 is mounted thereon as by the screw17. An enlarged portion 16 forms the top, or grip, of the valve stem.

The assembled device may be readily mounted in the intake opening of thedisposal conduit, the bottom portion of the sealing member 7 resting onthe internal shoulder formed on the inside of the intake disposalconduit, and the discharge opening 4 extending into said conduit beneathsaid shoulder. When it is desired to permit water and particles ofmatter in the water to flow into the disposal conduit, the valve stem ismanually raised until the shoulder formed by the termination of thesquared portion of the stem 14 passes the opening 13 in the top member,and the stem is turned into misalignment with said opening and the valve5 thus held out of contact with the seat 4. When it is desired to blockthe flow of water through the discharge opening 4, the stem is alignedwith the opening 13, and the valve 5 lowered into the discharge opening4. When it is desired to permit unrestricted flow into the disposalconduit, the entire device is lifted out of the discharge opening.

What I claim is:

1. A disposal intake control comprising, an upper and a lower memberseatable in a disposal intake opening, the lower member having an upperend and a lower end, a discharge opening at its lower end and anoutwardly projecting flange on the upper end thereof, a resilientsealing member mounted on said flange, internal threads in an upper wallof said lower member adjacent and inwardly of said flange, said uppermember having a lower rim and external threads adjacent said rim adaptedto be received by the said internal threads of said lower member, aplurality of drain openings in said upper member and a valve looselymounted in said upper member and adapted to seat in the dischargeopening in said lower member said upper member and said lower membereach being fundamentally hemispherical in shape and joining together bysaid internal and said external threads to form an essentiallyball-shaped control unit.

2. The device defined by claim 1 wherein there is a squared opening insaid upper member, said valve having a valve stem, the upper portion ofsaid stem being squared and being adapted to fit through said squaredopening in said upper member.

3. The device defined in claim 1 wherein said resilient sealing memberconsists of an annular member having an internal annular slot in whichthe flange of said lower member is mounted.

4. The device defined in claim 1 wherein said discharge opening in thelower member is inwardly tapered and forms a valve seat, the outerperiphery of said valve being inwardly and downwardly tapered to form aclose fit in said seat.
